Answer:
When deformed, it returns to its original shape
Explanation:
- A spring is elastic.
- Elasticity is the property of a material to regain its shape after having been deformed.
- It means that when the force is doubled, the amount of deformation in it gets doubled.
- Hence, the correct option is (b) " When deformed, it returns to its original shape".
Answer:
If the frequency is doubled the wavelength is only half as long.If you put your fingertip in a pool of water and repeatedly move it up and down,you will create circular water waves.
Hope this helps!!!
Complete Question:
Suppose that an asteroid traveling straight toward the center of the earth were to collide with our planet at the equator and bury itself just below the surface. What would have to be the mass of this asteroid, in terms of the earth’s mass M, for the day to become 25.0% longer than it presently is as a result of the collision? Assume that the asteroid is very small compared to the earth and that the earth is uniform throughout.
Answer:
m = 0.001 M

Answer:
h = 10 cm
Explanation:
The magnification produced by a mirror is given by :
h' is the image size and h is the object size
We have, h = 10 cm, m = +1
So,
So, the size off the object is same as that of the size of the image i.e. 10 cm.
